In recent years, there has been growing interest among researchers in exploring approximate number sense (ANS)—the ability to estimate and discriminate quantities without the use of symbols. Despite the growing number of studies on ANS, there have been no cross‐cultural longitudinal studies to estimate both the development of ANS and the cross‐cultural differences in ANS growth trajectories. In this study, we aimed to estimate the developmental trajectories of ANS from the beginning of formal education to the end of elementary school in two countries, Russia and Kyrgyzstan, which have similar organization of their educational systems but differences in socioeconomic status (SES) and in the results of large‐scale educational assessments. To assess the developmental trajectories of ANS, we used a four‐wave longitudinal study with 416 participants from two countries and applied the mixed effect growth approach and the latent class growth approach. Our analysis revealed that the rate of growth in ANS accuracy was higher for the Russian sample than for the Kyrgyz sample and that this difference remained significant even after controlling for fluid intelligence. We identified two latent classes of growth trajectories: the first class had a significant growth in ANS, whereas the second class had no growth. Comparing the distribution of latent classes within the two countries revealed that there was a significantly larger proportion of schoolchildren from the second class in Kyrgyzstan than in Russia.  相似文献

Using a questionnaire adapted from Arnett and Padilla‐Walker (2015), the authors examined the concept of adulthood among 366 Iranian emerging adults ages 17 to 29. Results suggested that the concept and criteria of adulthood are influenced by the cultural context. Implications for practice and recommendations for future research are discussed.  相似文献

橡胶手错觉是一种健康个体将非肉体的假手视为自己真实身体的一部分的体验, 这种错觉可以通过同时轻刷被试面前可见的橡胶手及其不可见的真手而产生.橡胶手错觉已成为一种研究身体拥有感的重要范式, 其产生机制可以分为“自下而上的认知匹配”与“自上而下的认知匹配”两种加工方式.前者涉及视觉与触觉刺激的同步性; 而后者涉及被试心中预存的身体意象与身体图式(包括真假手之间模态特征,位置空间的相似性).综合上述证据, 身体模型假说与个人边缘空间理论进一步为拥有感产生的复杂机制提供了整合两种加工方式的解释.橡胶手错觉范式已经被用于探索精神分裂症患者等特殊被试病理分析,错觉产生和心理特质之间的关系, 以及神经外科和术后恢复上.未来的研究应该更加重视范式本身的拓展, 应用虚拟现实技术来提高身体模态的仿真效果, 利用橡胶手拥有感的易感性作为筛选与预测身体意象障碍疾病的指标.  相似文献

This qualitative study explored the perceptions and experiences of Black female doctoral students at predominantly White institutions and their impact on academic persistence and overall well‐being. Fifteen Black female doctoral students participated in semistructured interviews, and each one was administered a demographic questionnaire and was extended an opportunity to participate in member checking. All data collected from the semistructured interviews, demographic questionnaires, and member‐checking exercises were analyzed using Black feminist thought as an interpretive lens. Whereas several themes emerged and are discussed in previous articles (Shavers & Moore, 2014a, 2014b), this article focused on the “Perpetual Outsider” theme, comprising the following subthemes: (a) unwelcoming spaces, (b) tokenism, and (c) outsiders at home. Implications are offered based on identity, support systems, and group counseling. Este estudio cualitativo exploró las percepciones y experiencias de estudiantes negras de doctorado en instituciones predominantemente blancas, así como su impacto en la persistencia académica y bienestar general. Quince estudiantes negras de doctorado participaron en entrevistas semiestructuradas, y a cada una de ellas se les administró un cuestionario demográfico y se les ofreció la oportunidad de participar en seguimientos de miembros. Todos los datos recopilados a partir de las entrevistas semiestructuradas, los cuestionarios demográficos y los ejercicios de seguimiento de miembros fueron analizados e interpretados desde la perspectiva del pensamiento feminista negro. Aunque surgieron varios temas que se comentan en artículos anteriores (Shavers & Moore, 2014a, 2014b), este artículo se centra en el tema del “Forastero perpetuo”, que incluye los siguientes subtemas: (a) espacios hostiles, (b) representación simbólica y (c) forasteros en casa. Se ofrecen implicaciones basadas en la identidad, sistemas de apoyo y consejería de grupo.  相似文献

主动控制感指预计动作和实际感觉反馈匹配会产生一种控制自己动作、作用于环境的主观体验, 是人类心理活动的基本特征之一。本文系统介绍主动控制感的测量方式, 尤其是主动动作的时间压缩效应这一内隐手段; 并从主观意识、动作的发生方式和动作结果特征三个方面探讨主动控制感的影响因素。基于动作的比较器模型, 解释主动控制感的产生原因; 并提供了主动控制感的认知神经脑机制的证据, 强调额叶和顶叶在主动控制感中的作用。未来研究应该更加注重外显与内隐测量的一致性, 特殊群体以及主动控制感的脑网络研究。  相似文献

The paper argues, that a direct formalization of the way common sense thinks about the numerical identity of enduring entities, requires that traditional predicate logic is developed. If everyday language mirrors the world, then persons, organisms, organs, cells, and ordinary material things can lose some parts but nonetheless remain numerically exactly the same entity. In order to formalize this view, two new logical operators are introduced; and they bring with them some non-standard syntax. One of the operators is called ‘the instantiation operator’; it is needed because the existential quantifier and its traditional relatives cannot do the job required. The other operator is called ‘the form-on-matter operator’, and it allows an individual (an instance of a form) to stay the same even though some of its parts (its constituting matter) is taken away from it. Also, a certain kind of predicates, called ‘nature terms’, is needed in order to represent what gives a particular its kind of identity. Both the operators and the nature terms introduced can be used in constructions of formal languages and formal systems, but no such constructions are made in the paper. The paper is structured as a comment on the philosophical problem called ‘the problem of the cats Tibbles and Tib’.  相似文献

Frege argued that a predicate was a functional expression and the reference of it a concept, which as a predicative function had one or more empty places and was thus incomplete. Frege’s view gives rise to what has been known as the paradox of the concept “horse.” In order to resolve this paradox, I argue for an opposite view which retains the point that a predicate is a function, i.e. that a predicative function is complete in a sense. Specifically speaking, a predicate performing the function of a predicate has at least one empty place and has no reference, while a predicate performing the function of a subject does not have any empty place but does have a reference. Frege not only regarded a concept with one or more empty places as the reference of a predicate but also took a set of objects without any empty place to be the extension of a concept with one or more empty places. Thus, it presents a complex relationship between the reference of a predicate and its corresponding extension, leading to disharmony in his theory. I argue that this is because there is a major defect in Frege’s theory of meaning, namely the neglect of common names. What he called extensions of concepts are actually extensions of common names, and the references of predicates and the extensions of common names have a substantial difference despite being closely related.  相似文献

涵义语义与关于概称句推理的词项逻辑   总被引:1,自引:0,他引:1  
概称句推理具有以词项为单位的特征并且词项的涵义在其中起到了重要的作用。已有的处理用A一表达式表达涵义,不够简洁和自然。亚里斯多德三段论是一种词项逻辑,但它是外延的和单调的。这两方面的情况使得有必要考虑新的词项逻辑。涵义语义的基本观点是:语词首先表达的是涵义,通过涵义的作用,语词有了指称,表达概念。概称句三段论是更为常用的推理,有两个基本形式GAG和Gaa。在涵义语义的基础上建立的系统GAG和Gaa是关于这两种推理的公理系统。  相似文献

ABSTRACT— Since the discovery of head-direction cells in nonhuman mammals, we have learned a great deal about how an internal compass-like system functions in the mammalian brain. In contrast, we know very little about how this system operates in humans—or, for that matter, whether humans even have an internal compass for computing body heading. This article reviews a recent line of inquiry that uses animal models of head-direction-system functioning to motivate behavioral research on human sense of direction.  相似文献

为了考察物体受力分析图正、误样例的相似程度以及被试对错误受力分析的认知加工(即对错误受力分析的辨别、解释和改正)水平对物体受力分析规则正误样例组合学习迁移效果的影响,以初中三年级学生为被试进行两项实验研究。实验结果表明:在物体受力分析图正误样例组合学习中存在明显的相似性效应,即正、误样例的相似程度越高,学习迁移的效果越好;对错误受力分析进行"改正"加工的学习迁移效果明显优于对错误的"辨别"加工,即存在明显的认知加工深度效应。  相似文献
